Cut to Air

A "cannot ventilate, cannot intubate" scenario is a rare, high-risk anesthesia event. Cricothyrotomy is the final step, but anesthesia training and maintenance of surgical airway skills is variable. The ability to "cut to air" when one performs a cricothyrotomy may be all that prevents a patient from experiencing anoxic brain injury or death. Forty-three Certified Registered Nurse Anesthetists (CRNAs) performed emergency cricothyrotomies on a simulation manikin. Three techniques were available: (1) cricothyrotomy kit, (2) scalpel and tracheostomy, and (3) scalpel/bougie/endotracheal tube. Technique selection and performance were recorded until successful confirmation of placement was achieved in less than 2 minutes. Confidence levels performing cricothyrotomy were also measured before and after simulation. Most CRNAs (53.5%) selected the cricothyrotomy kit, and all but 1 completed the cricothyrotomy in under 2 minutes. The scalpel/bougie/endotracheal tube combination was the fastest, with an average completion time of 86.6 seconds. The confidence of CRNAs in performing a successful cricothyrotomy in less than 2 minutes was significantly increased (P ≤ .001). Simulating airway skills improved performance, speed, and confidence. Because not all CRNAs have had extensive education in performing surgical airways and practicing these skills, simulation may have additional value in developing and maintaining skills and confidence.
